2,3-Diaryl-3-imidazo[4,5-]pyridine derivatives as potential anticancer and anti-inflammatory agents.

In this study we examined the suitability of the -imidazo[4,5-]pyridine ring system in developing novel anticancer and anti-inflammatory agents incorporating a diaryl pharmacophore. Eight 2,3-diaryl-3-imidazo[4,5-]pyridine derivatives retrieved from our in-house database were evaluated for their cytotoxic activity against nine cancer cell lines. The results indicated that the compounds showed moderate cytotoxic activity against MCF-7, MDA-MB-468, K562 and SaOS2 cells, with K562 being the most sensitive among the four cancer cell lines.
